How can we characterize human generalization and distinguish it from generalization in machines?
Curr. Dir. Psychol. 34, 293-300 (2025)
People
appear to excel at generalization: They require little experience to
generalize their knowledge to new situations. But can we confidently
make such a conclusion? To make progress toward a better understanding,
we characterize human generalization by introducing three proposed
cognitive mechanisms allowing people to generalize: applying simple
rules, judging new objects by considering their similarity to previously
encountered objects, and applying abstract rules. We highlight the
systematicity with which people use these three mechanisms by, perhaps
surprisingly, focusing on failures of generalization. These failures
show that people prefer simple ways to generalize, even when simple is
not ideal. Together, these results can be subsumed under two proposed
stages: First, people infer what aspects of an environment are task
relevant, and second, while repeatedly carrying out the task, the mental
representations required to solve the task change. In this article, we
compare humans to contemporary AI systems. This comparison shows that AI
systems use the same generalization mechanisms as humans. However, they
differ from humans in the way they abstract patterns from observations
and apply these patterns to previously unknown objects—often resulting
in generalization performance that is superior to, but sometimes
inferior to, that of humans.
